Answer:
I like to compare them all the same. Put all the equations in slope intercept form y=mx+b
So you need to isolate y.
Step-by-step explanation:
Main equation to compare y=2/3x + 4
If they have the same slope they are parallel. If they have opposite reciprocal slopes then they are perpendicular.
First one is y=2x +12 neither
Second one is y= -3/2x -1 perpendicular
Third one is y= 2/3x - 1 parallel
Forth one is y= 2/3x + 11/3 parallel
Step-by-step explanation:
8k - 12 = 3
8k = 3 +12
8k = 15
k = 15/8
k = 1.875
In order to understand if the inequalities are always, never or sometimes true, you need to perform the calculations:
A) <span>9(x+2) > 9(x-3)
9x + 18 > 9x - 27
the two 9x cancel out and you get:
+18 > -27
which is always true.
B) <span>6x-13 < 6(x-2)
6x - 13 < 6x - 12</span>
</span><span>the two 6x cancel out and you get:
- 13 < -12
which is always true
C) </span><span>-6(2x-10) + 12x ≤ 180
-12x +60 +12x </span>≤ 180
-12x and +<span>12x cancel out and you get:
60 </span><span>≤ 180
which is always true.
All three cases are always true.</span>
